(1)  Recognized plant nutrients in addition to nitrogen, phosphoric acid and potash when mentioned in the labeling shall be registered and guaranteed. Sources of the elements guaranteed and proof of availability shall be provided the department upon request. The minimum percentages which will be considered for registration are as follows:

 

Element	%
Calcium (Ca)	1.00
Magnesium (Mg)	0.50
Sulfur (S)	1.00
Boron (B)	0.02
Chlorine (Cl)	0.10
Cobalt (Co)	0.0005
Copper (Cu)	0.05
Iron (Fe)	0.10
Manganese (Mn)	0.05
Molybdenum (Mo)	0.0005
Sodium (Na)	0.10
Zinc (Zn)	0.05

 

Guarantees or claims for the above listed plant nutrients are the only ones which may be accepted. Proposed labels and directions for use of the fertilizer shall be furnished with the application for registration upon request. Any of the above listed elements which are guaranteed shall appear in the order listed immediately following guarantees for the primary nutrients of nitrogen, phosphorus and potassium. When directions for use render the product ineffective (as a fertilizer)  the department will not register the product.

(2)  A warning or caution statement is required on the label for any product which contains 0.03% or more of boron in water soluble form. This statement shall carry the word "WARNING" or "CAUTION" conspicuously displayed, shall state the crop(s)  for which the fertilizer is to be used, and state that the use of the fertilizer on any other than those re-commended may result in serious injury to the crop(s)  .

(3)  Products containing 0.001% or more of molybdenum also require a warning statement on the label. This shall include the word "WARNING" or "CAUTION" and the statement that the application of fertilizers containing molybdenum may result in forage crops containing levels of molybdenum which are toxic to ruminant animals.

 

 

         EXAMPLES OF WARNING OR CAUTION STATEMENTS:

 

Boron:

 

(a)  Directions:   Apply this fertilizer at a maximum rate of 350 pounds per acre for Alfalfa or Red Cloverseed production. CAUTION: Do not use on other crops.   The boron may cause injury to them.

(b)  Caution: Apply this fertilizer at a maximum rate of 700 pounds per acre for Alfalfa or Red Clover seed production. Do not use on other crops; the boron may cause serious injury to them.

(c)  Warning: This fertilizer carries added Borox and is intended for use only on Alfalfa. Its use on any other crops or under conditions other than those recommended may result in serious injury to the crops.

 

Molybdenum:

(a)  Caution: This fertilizer is to be used only on soil which responds to molybdenum. Crops high in molybdenum are toxic to grazing animals (ruminants)  .

(2)  Specialty fertilizer labels containing the following information, if not appearing on the face or display side in a readable and conspicuous form shall occupy at least the upper-third of a side of the container and shall be considered the label.

(a)  Net weight

(b)  Brand and grade

(c)  Guaranteed analysis:
